i tried giving tmux a go but there is a period where you're kinda going in and out of a tool, maybe not coming back to it for weeks at a time, this is why imo herdr is a really good tool - it doesn't punish you for not remembering the bindings, everything is clickable and as you go you can decide which bindings to learn and commit to instinct when required. I believe all TUIs should be like this from now on. This is also what makes opencode so great/sticky. Great work herdr team, I've only used it for a few days but I know I will be using this for a long time to come.

Zellij has context sensitive hint bar that shows possible key bindings. You can turn it off, but by default it's there.
